8 Troubleshooting
The troubleshooting instructions in this chapter will help you to quickly find
and correct the most common faults that may occur when using the welder.
The error message list is useful in interpreting any error messages shown on
the display of the welder (red display background), see 8.1. Fault tracing ta-
ble. A red error message automatically stops the welder. The fault-tracing
table is useful when tracing welder faults. The table presents the most com-
mon faults and their possible causes.
There are also information messages (yellow display background),
see 8.2 Display information messages.
When yellow information messages are shown, the welder can still be used.
WARNING! All electrical connections must be carried out by a qualified

WARNING! Unplug the welder from the wall outlet before servicing,
cleaning or maintenance. Risk for electrical shock.
WARNING! Never remove any covers or perform any work to the welder
without unplugging the welder from the wall outlet. Risk for electrical
shock.
